I got have a good look (and play) with the Microsoft Builder app and native printer installation while at the 'Build' conference. It is pretty slick but when people were not there to keep all the the 3D printers (new metal print bots) running there were a lot of mid-air prints going on. Definitely not a consumer level feature yet.

This sounds like a good advance though, I don't think M$ is that interested in your print files and if there were how safe do you think your files are on your hard drive.. (just to up the tension on the conspiracy theory)

I'm pretty sure that if I told some clients that we used automated processes provided by microsoft they'd fire us.

Thankfully we aren't dependent on netfab to fix (and in some cases break further) our models.But for the rest of you.... tread carefully. It does look like a quality product though. Not the print driver (never seen that) though... as for airprinting.. I see a LOT of that with all solutions. Isn't air printing the norm?
